Services Offered by Furnace Repair Companies

Your local furnace repair provider offers a number of services to keep your system working efficiently and effectively. We’ve outlined the most common ones below.

Repair and Maintenance

A timely repair restores the furnace's function, extends its life span, and optimizes energy efficiency. Furnace repair providers can diagnose and repair any furnace issue, such as a clogged air filter, malfunctioning thermostat, or broken blower motor. Qualified HVAC technicians examine and fix individual problems including damaged heat exchangers, malfunctioning thermostats, possible gas leaks, or faulty ignitions. Your furnace repair company can also perform routine HVAC maintenance to help avoid unnecessary breakdowns. Your technician will ensure that all components function properly by inspecting your furnace, cleaning it, replacing air filters, and lubricating moving parts.

Installation

HVAC companies can also install a new furnace. You may want a new system if yours is beyond repair or if you want to upgrade to a more energy-efficient option such as a heat pump. Your technician will first assess your home's layout and heating needs before recommending the best furnace model for your requirements and budget. Your HVAC expert can integrate a new system with your existing air ducts and thermostat. They're trained on industry safety protocols and standards for proper furnace replacement and connection. Post-installation, your technician will do one last inspection to ensure your furnace runs properly.

Inspection

You should schedule an inspection by a furnace repair provider if you notice your furnace failing to turn on. A technician will inspect each of the furnace's components to identify potential causes. The inspection typically includes checking for any gas or fuel leaks, inspecting the burner and ignition system, examining the heat exchanger for cracks or damage, cleaning and replacing air filters, and testing the thermostat's accuracy. The technician verifies the heating system's safety and efficiency, making necessary adjustments or repairs. Routine, annual furnace tune-ups ensure peak performance, help avoid potential breakdowns, and promote a safe living environment during cold winters.

Emergency Services

Emergency furnace repair services help with unexpected breakdowns, malfunctions, or safety concerns. Many providers offer these around-the-clock services to help get your system back up and running promptly any time of the day or night. Emergency services may cost more than scheduled service, but it's worth it to protect your health. If your furnace fails during extreme weather conditions, and you can't open windows for fresh air, it can cause serious discomfort and health risks due to decreased indoor air quality.

Factors To Consider When Choosing a Local O'Fallon Furnace Repair Service

There are a number of important considerations for choosing a local O'Fallon furnace repair provider. We review some key factors below.

  • Cost: Compare pricing and services offered by several O'Fallon furnace repair companies. Look for transparent and competitive pricing while avoiding extremely low-cost options. Abnormally low prices may indicate that a company is making up the difference by compromising the quality of work or materials.
  • Guarantees: Guarantees and warranties provide peace of mind should issues arise after a repair. Reliable furnace repair providers should back their work with guarantees or warranties for both their workmanship and replacement parts.
  • Licensing: You want to use a furnace repair provider that holds all the required licenses and certifications. In Missouri, your HVAC contractor must obtain certification from your local city or municipal government. Proper licensing helps ensure that technicians are qualified to safely handle furnace repairs.
  • Qualifications: Inquire about a company's training policies as well as the experience of its technicians. Companies that promote ongoing training tend to have technicians that use the latest repair techniques. Look for a company that employs well-trained technicians with experience working with various furnace makes and models.
  • Reputation and reviews: Research the company's reputation by checking online reviews and testimonials from previous customers. A strong positive reputation is a likely indicator of quality services. Pay attention to how the provider addresses negative feedback or complaints, as this reflects its commitment to customer satisfaction.

How Much Does a Furnace Repair Cost?

Certain factors affect the cost of furnace repair. These include the extent of the damage, the type of HVAC unit, and price of replacement parts. Furnace repair costs $424 on average, although the prices can vary depending on your situation. Below are some common furnace repairs and their average costs.

  • Broken thermostat: $79–$394
  • Cleaning: $47–$63
  • Cracked heat exchanger: $1,577–$2,759
  • Damaged blower bearings: $24–$118
  • Damaged blower belt: $24–$87
